ORNO PV splitter 3x MC4 T-type for photovoltaic panels, 3-branch MC4 connector

ORNO PV splitter 3x MC4 T-type for photovoltaic panels, 3-branch MC4 connector is a compact DC junction designed for photovoltaic array wiring. It provides a single-input to three-output or three-input to single-output arrangement while keeping standard MC4 polarity and locking mechanism. The device is intended to create secure, weather-resistant electrical connections between solar panels and downstream cabling in rooftop or ground-mounted systems.

Advantages

This ORNO T-type PV splitter supports three branches using standard MC4 connectors to ensure compatibility with common solar cables and modules. The splitter preserves polarity and locking features of MC4 plugs to maintain safe, low-resistance contacts. Its design enables straightforward integration into existing PV strings without custom tools or modifications and provides a compact solution for distributing DC current reliably in outdoor installations.

Suitable for

• Splitting one PV string output to feed three inverter inputs or charge controller circuits
• Combining up to three panel strings into a single feed line where system design allows
• Roof-mounted and ground-mounted solar installations requiring compact DC distribution
• Temporary or permanent PV array reconfiguration and testing

Key specifications

• Connector type: MC4-compatible T-branch with three MC4 interfaces
• Contact configuration: single pole DC splitting/combining for photovoltaic use
• Ingress protection: designed for outdoor use with weather-resistant coupling (typical for MC4 systems)
• Material characteristics: durable plastic housing with UV resistance and corrosion-resistant contacts
• Electrical performance: suitable for standard PV DC voltages and currents when used within MC4 system ratings

How to use

Align MC4 plugs with the splitter sockets and push until the locking mechanism clicks to secure each connection. Ensure correct polarity by matching positive to positive and negative to negative connectors; MC4 design prevents improper mating when used as intended. Install the splitter in a location protected from excessive mechanical stress, and route cables to avoid sharp bends or pinch points. If combining multiple strings, verify system voltage and current limits and ensure fusing or protection is in place according to applicable electrical standards.

Usage recommendations

Inspect connectors for dirt, damage, or corrosion before installation. Use only MC4-compatible cables and maintain manufacturer-recommended cable sizes and overcurrent protection. For permanent rooftop installations, position the splitter to minimize prolonged exposure to standing water and ensure connections remain accessible for inspection and maintenance.
